Glulam portal frame
Glulam portal frame
(OP)
I'm designing a portal frame structure similar to third type on the picture.

Mine also has a horizontal tension element (a tie) at the level of knee joint (column-beam) connecting both columns. Knee joint is not glued but has to be mechanically connected. Base connection to the foundation is also rigid because my frame is quite high and I need it to stiffen it against lateral deformation.
My question is what kind of knee joint would you design. I'm considering a system with self-tapping screws in tension like ZD-Platte or glued in metal sheets like HSK-System.
I cannot use double beam or column.
How do you usually design a rigid connection? With bolts? For that you usually need to make the wooden members bigger to make it work and still stiffness stays an issue.
